Malangizo Okhudza Kusankha Sera ya Mafakitale: Kupaka, Inki ndi zina zambiri

 

Pakukula kosalekeza kwa makampani opanga utoto, kukonza magwiridwe antchito a utoto nthawi zonse kwakhala cholinga chachikulu, ndi zowonjezera sera zikuchita gawo lofunika kwambiri. Kupanga ndi kugwiritsa ntchito kwawo kumakhudza kwambiri mtundu wa utoto. Kuyambira sera zachilengedwe zoyambirira mpaka sera zopangidwa ndi mamolekyulu ochepa, ndipo tsopano mpaka sera zopangidwa ndi mamolekyulu ochepa, kusintha kwa utoto kukuwonetsa kupita patsogolo kwa ukadaulo wopaka utoto. Nkhaniyi ikuyang'ana kwambiri pakugwiritsa ntchito kwatsopano sera zopangidwa ndi mamolekyulu ochepa mu utoto, kufufuza zabwino zake, njira zosankhira, ndi zochitika wamba zogwiritsira ntchito. Cholinga chake ndi kupereka maumboni okwanira komanso othandiza kwa akatswiri amakampani, kuthandiza zinthu zopangira utoto kuti zikwaniritse kupambana pakukana kukanda, kukana kuwonongeka, kukana kutentha, komanso kukana nyengo, potero kulimbikitsa kupanga kosawononga chilengedwe komanso chitukuko chapamwamba.

① Mavuto Atatu Aakulu a Sera mu Kugwiritsa Ntchito Zopaka Zapamwamba:
• Vuto Lolephera Kutentha Kwambiri: Mu zophimba zamagalimoto/zipangizo, mamolekyu a sera amafewa kutentha >150°C, zomwe zimapangitsa kuti 50% iwonongeke komanso kulimba pang'ono.
• Vuto Lochepa la Kugwira Ntchito Pamwamba: Sera yachikhalidwe singathe kuthana ndi nthawi imodzi ndi kukana kutsetsereka, kukana kukanda, kukana kutopa, kumva kukhudza, ndi zofunikira zina zambiri, zomwe zimalepheretsa kugwiritsa ntchito utoto.
• Lamulo Loletsa Kupha la EU: Likukhudza mitundu yoposa 10,000 ya PFAS (kuphatikizapo ma fluoropolymers, monga omwe amagwiritsidwa ntchito popaka zinthu zosalowa madzi).
2025: Kulemba pempho ndi pempho loti anthu apereke ndemanga.
2026-2027: Kutsimikizika kwathunthu komwe kukuyembekezeka.

② Kupititsa patsogolo Mphamvu ya Sera Yopangidwa ndi Ma Molecular Yokhala ndi Ma Dimension Anayi:
• Kukana Kuwonongeka/Kukanda: Sera yosinthidwa kwambiri ya mamolekyulu imathandizira kwambiri kukana kuwonongeka kwa utoto, ndi chiŵerengero chokwera cha mpaka 50%, zomwe zimapangitsa kuti utoto ukhale wautali.
• Kugwira Ntchito Pamwamba: Kumathandiza kuti munthu azitha kugwira zinthu, kusatsetsereka, kusachita zinthu mopitirira muyeso, komanso kusachita zinthu mopitirira muyeso, pakati pa zinthu zina zambiri, ndi kusintha kwa 30% pakugwira ntchito pamwamba kuti kukwaniritse zosowa zosiyanasiyana.
• Kukana Kutentha/Nyengo: Sera yosinthidwa kwambiri imakhala ndi malo osungunuka opitirira 260°C, zomwe zimapangitsa kuti kutentha/nyengo zisamatenthe ndi 20%, zomwe zimapangitsa kuti ntchito isamavutike m'malo ovuta.
• Kulimba kwa kutentha kwambiri komanso kukana kukalamba kumapangitsa kuti ikhale njira yabwino yogwiritsira ntchito sera zochokera ku PTFE.

Momwe Mungasankhire WAX ​​Yoyenera

Kusungunuka kwa sera kumatsimikizira malo ake ogwiritsira ntchito komanso kukhazikika kwa ntchito yake:

Malo Osungunula	Mapulogalamu	Zamalonda Zachizolowezi
<100℃	Kupukuta utoto wamatabwaKuphimba kotsika kutentha kochiritsa	Sera ya CarnaubaSera ya njuchi
100–300℃	Chophimba cha cholinga chachikulu	Sera ya PE, sera ya Fischer Tropsch, PTFE, sera ya polima
>300℃	Chophimba kutentha kwambiri	PTFE, sera ya polima yosinthidwa

 

Kukula kwa tinthu ta sera kumakhudza mwachindunji kunyezimira, kumva, ndi magwiridwe antchito oteteza a chophimbacho:

Kukula kwa Tinthu (D50)	Zotsatira pa zokutira	Mapulogalamu
<1μm	Palibe kukhudza kulikonse pa gloss, zomwe zimapangitsa kuti ikhale yofewa:	Chovala chapamwamba chowala kwambiri, chophimba chamagetsi cha zinthu zamagetsi
3–7μm	Kumaliza pang'ono kopanda matte kumawonjezera kukana kukanda	Utoto wa mipando, utoto wa pulasitiki
8–15μm	Kumaliza kwakukulu kwa matte, kukana kuvala bwino	Utoto wosakhwima, utoto wapansi
>25μm	Pangani mawonekedwe a mchenga	Utoto waluso, utoto wapadera

 

Polarity imatsimikizira kugwirizana ndi magwiridwe antchito a sera ndi makina a utomoni:

Sera ya polarity yapamwamba (monga sera ya polyolefin yokhala ndi acid, sera ya polymer yosinthidwa): imagwirizana bwino ndipo imatha kufalikira ndi ma resin a polar (monga machitidwe opangidwa ndi madzi, epoxy, polyurethane), imawongolera bwino mawonekedwe amakina a chophimbacho, imawonjezera kumatira ndi mphamvu pamwamba;

Sera yotsika ya polarity (monga sera ya PE, PTFE): imasamuka kupita pamwamba pa chophimbacho kuti ipange gawo losalowerera madzi, losagwira madzi, losagwirana, komanso losamva kugwira.

 

Mitundu yosiyanasiyana ya zowonjezera sera ndi yoyenera njira zosiyanasiyana zopangira:

Mafomu	Kukonza	Zabwino	Zoyipa
Sera yopangidwa ndi micronized	Kupera kwa ndegeKuumitsa kwa utsi	100% zokhutira zolimba Palibe chomwe chingakhudze kukana madzi	Zovuta kufalitsa
Kutulutsa sera	Kusakaniza kwa emulsification	Zosavuta kugwiritsa ntchitoKukula kwa tinthu tofanana	Chosakaniza cha emulsifier chilipoZingachepetse kukana madzi
Kusakaniza kwa sera	Kupera konyowa	Kukhazikika kwabwinoZosavuta kugwiritsa ntchito	Chosungunulira chili ndiVOC Yapamwamba

 

Kugwiritsa ntchito kwachizolowezi ndi njira yowonjezera sera/machiritso:

Mapulogalamu	Zofunikira zazikulu	Mitundu yovomerezeka	Mlingo
Kuphimba magalimoto	Yolimba kukanda, yosalala kukhudza	Sera ya PE, sera ya Carnauba	0.5-2%
Chitsulo chosindikizidwa, zinthu zozungulira	Chokwanira cholimba komanso cholimba (<0.2)	Sera ya polimaSera ya PE/PTFE	0.5-1.5%
Utoto wa pansi	Kusatopa komanso kusagwirizana ndi kukokoloka kwa mchenga	PP, sera ya polima	1-3%
Chophimba cha mafakitale	Kusavala bwino komanso kukana kukanda	Sera ya polimaSera ya PE/PTFE	0.8-1.5%
Kuphimba ufa	Mafuta odzola, kukana kukanda, ndi kuchotsa fumbi	PE, FT, PP, PA, PTFE	Palibe
Inki	Chokwanira cholimba komanso chotsika cha kukangana	Malinga ndi zosowa zanu	Palibe

 

Kampani yathu imadziwika bwino popereka mitundu yosiyanasiyana ya sera yopangidwa (Polymer).
